Mike 'The Situation' Sorrentino admits he is struggling with sobriety.The 'Jersey Shore' star checked into rehab earlier this year after getting addicted to painkillers following a neck injury he suffered while competing on 'Dancing with the Stars' and although he is healthy now, he admits it has been a tough battle. He is quoted by In Touch Weekly magazine as saying: ''I'm doing my best. All I can do is take it one day at a time. ''I'm completely sober now. This is the healthiest I've been in a very long time.'' Although it was feared filming the final season of 'Jersey Shore' would lead to Mike falling off the wagon, he remained sober throughout the MTV show and producers made sure to help him with his goal. A programme source said: ''The film crew were like his babysitters and helped him stay in check. It really helped him through his recovery.'' Mike, 31, recently confessed rehab was the hardest challenge he has ever had to face in his life, and is proud of himself for coming through it. He said: ''I was dependent on prescription pills. I knew I needed help and I went to rehab. ''Rehab is the most unbearable, unpleasant experience you could possibly go through but I am the cleanest and healthiest I have ever been since I was 21 or so.''
